And NONE of them is a monkey, which kinda makes the vid linked to in the OP a load of crap (although I can see some merit in parts of it).
I reckon the guy in the video used the term "monkey" for effect, rather than accuracy. The sort of people who it is aimed at are the sort of anti-darwin types who possibly won't differentiate, in biological classification, between apes and monkies. If they accept the biological classification used to describe the difference between apes and monkies, they're accepting the classification that implies the relationship between man and ape....and everyone knows monkies throws faeces, so bang! Monkey is a more effective term.
